qTvTI-OBYBIDEB, AND ronnnsr J; coUcH, or ROCHESTER, NEW'YonK, AssIGNons To ".fjuseful Improvements in Mangles; and we'- do hereby declare the following to be a full',

clear,and exact description of the saine, reference being had 'to the accompanying drawngs,gform1ng av part of' this specication, ,Wand -..to the A`reference-numerals marked I thereon. Y v

Our invention .relates to mangles, .and

l more particularly to the 'type of machine ein- -bodying a steam chest, together with .a plurality of ironing rolls cooperating with one surface of the chest, and an apron or belt cooperating with another surface of the chest, and it has for its purpose to provide an improved means 'for controlling the apron or belt, whereby it is automatically slackened or loosened to relieve it from pressure i against the steam chest whenever the rolls are elevated awayfrom the chest.

A further purpose of the invention is to afford means that will effect slackening of the apron only during'a portion of the elevating movement of the rolls, without caus- A ing any decrease in the tension ofthe apron p during the initial elevating, movement of the ironing rolls away from the chest,.and in this way allowing more or less play of the 'ironing rolls relatively to the steam chest while'mainainingthe apron 'at a constant B5 pressure, and relieving it only when the rolls are moved a considerable distance away from the chest. f 1

To these `and other ends thelinvention consists in certain improvements and combina 40 tions of parts all as `will be hereinafter more fully described, the novel features being l pointed out Yin the claims at the end of the speciticat' n:

lOperatin Patented Mar. in, i .i

I machine, A designates a frame upon which is mounted the steam chest B, provided upon its upper surface `with a series of depres'? sions, in which engage ironing rolls C. The

rolls C are mounted upon a holder4 D, being Journaled in boxes E which are arranged on the holder, and the latter is movableyverti'- cally with relation. tothe frame Ain order to carry the rolls G toward and away from the steam chest. Each of the rolls C 'is mounted in boxes E, which are 'held in place on the holder by means of rods G, these being somewhat smaller-than the openings in the boxes through which they pass vin order to permit a slight lost motion or vertical play between the holder and the ironing rolls. This enables the rolls to engage the steam chest with a slightly yielding pressure,

the pressure being exerted by means of,

springs H which engage the boxes G and may be adjusted asto'tension bythe foli 4 lowers I.

In order to actuate the holder D, Soas tod.`

effect movement of theironingrolls away from' the steam chest when this is necessary for anyv purpose, We employ roll elevating means, which may be of an suitable character,v and preferably comprises one or more shafts J, J1 upon which are mounted eccenf f trics that operate, "when the shafts are rotated, to eliect vertical movement of the cont necting rods L, the'latter being suitablyy connected at their upper ends to the holder D. The shafts'J J1 may be operated in any de 'sirable manner, and to this end are provided with worm gears M, engaged'by worms N mounted upon a drive shaft O, which is adapted to be driven byany convenient form ofgearing. Y A l beneath the steam chest is a .pair of a rens or belts designated `generally at P an Q. The upper apron P engages' the lower surface of the steam chest in the mannershown, while the lower apron'Q is arranged solthat its upper portion' engages v Y the lower lap of the apron P, guiding rolls being provided'to controlthe path .of travel of the aprons as usual in this type. of niachine When the ironing rolls are elevating away from the steam' chest, or it becomes 4necessary to stop the' operation of thema- 'chine for any len h Aof tme it is desirable that the aprons instantly slackened, so

:tot

that the upper apron will not be held against steam ,with Vsullicient pressure v apron "o ,ofanylv articles thatimayl be inthe rcause scorching or burning eithcroftbe machine.' To this end weprovi'de guiding' rol lsfi'ofr "thegaprons, that are mountedv upon amovable, support, which is actuated from' the? roll elevating meanshby devices that perm'itthe said support to remain stationary during the preliminary oi initial vertical movement ot the ironing rolls, and effect 4sullicient movement of the support' during'v the latter part of-the upward'movement of the vironing rolls torelieve theaprons sufficiently i Tothis vend, we may vemploy a' support consisting of brackets R which arev piyotally` inpunted at a and are .provided ith slots ,orv cutaway portions to receivev "th k1adjiistz'i'l'ole"boxes,c in'which the guiding "'ollf cl 'and .earewmounted e The brackets y tare, preferably provided with projections,

lfora'nti-friction rollers f, -ivhich'are arranged to" engagev the edges .of cams g, upon Vthe shaft-J1, the parts being normally in the positfioii-r shown`r in Fig. 1 in which the. api-on' guiding: roll support is in a nearly: vertical', position, `the aprons being stretchedv tautf Cams 'g are of such a shape that dury ing lawpartial vrotation yof the shavftpJl,l no

movement of the apron guiding roll supportwti'ikes'place, and the pressure of the apron is not chan-ged until theshaft J1- is rotated far enough to vbring the narrower'y 'i portion of they cam into engagement with the support, vi-*liereupon the latter is.per

mitted to be lowered to a nearly horizontal position, and the apronsare correspondingly e s lckened' This allows the ironing rolls to, `floelelevated and lowered slightly, with lre" spect to :the steam Ychest, for varying thickness-es 4of'articles,- without affecting the pres- 'sure of the aprons and'this enables us to obtain the same *ironing effect for articlesr l i of any thickness that may pass through the c machine, the pressure of the aprons notV be'- ing changed until the ironing rolls have been elevated a considerable distanceawayvfrom the cl'fest when the ironing rolls arc-lowered, .the reverse operation from What has .been

described takesyplaee.

`It is to beunderstood thatA the invention, is` 'not limited, in .its broadest' aspect, to the particular embodiment disclosed or to any 'particular-form of connectionvbetween the roll' elevating means and the apron guiding v rolls, as We intend tocover by this application `any 'structurewhich is the equivalent of what' we have shown in so far asit'may yinciule a means fordecreasing the pressure or -tension of an apron during the latter part of the upivardmovement ofl theironing rolls, and permitting a certain amount of relative movement between the ironing rolls and chest without affecting the tension of the apron. We claimas our invention: l j

1. In'an ironing machine,'the combinacoperatiiig therewith, of roll4 elevatingmeans', apron guiding rolls, a movable supiport on which the apron guiding rolls are',

mountethand a variable connection between tion" with a steam vchest and ironing rolls said support andthe roll elevtingfmeaiis i actin'gto permit the support to remain sta` tional-y during the initial part of the elevating movement ofthe rollsy and to' move it during-the remaining of such movement.

2. In an ironingmachine,A the combination f with a steam chest and ironing rolls coper-fi. ating therewith,l ot roll elevat1ng'means, e

apron guiding rolls, amovablesupport ony which the apron guidingv rolls are'mourited,

and -a variable connectionbetween said sup-V port and the roll elevating meansqacting to. move the supportati an increasing rate asv the rolls'are elevated.

' 3. In an ironing machine, the combination with a steam chest and ironing rolls coperati'fi'g therewith, of roll f elevating means, apron guiding rolls, a movable support on which the apron guiding, rolls are mounted,

and a cam driven by the roll elevating means'.

and operating on the support toymovew it a during a portion only of the elevating movement of the rolls. GoTTLoBy BINDER.
